Reassessing Kuraray (TSE:3405) Valuation After New PFAS Water Treatment Patent Win

Kuraray (TSE:3405) just gained fresh attention after its subsidiary Calgon Carbon secured a new U.S. patent for using reactivated carbon to remove PFAS from water, strengthening its position in regulatory driven treatment demand.

See our latest analysis for Kuraray.

That patent win lands at a tricky time for Kuraray, with the share price down sharply year to date but still supported by a solid three year total shareholder return. This suggests long term holders have not lost faith even as short term momentum has cooled.

If this shift in sentiment has you reassessing your watchlist, it could be a good moment to explore fast growing stocks with high insider ownership as you search for the next wave of potential compounders.

With the share price sliding this year despite robust multi year returns, and analyst targets sitting well above today’s level, is Kuraray quietly undervalued or is the market already baking in the next leg of growth?

Price-to-Earnings of 61x: Is it justified?

On a price-to-earnings basis, Kuraray looks expensive at a 61x multiple, with a share price of ¥1558.5 and peers trading on far lower earnings multiples.

The price to earnings ratio compares the company’s market value to its current earnings and is a common way to judge how much investors are willing to pay for each unit of profit. For a diversified chemicals and materials group like Kuraray, this multiple often reflects expectations around future margin recovery and earnings growth rather than just today’s compressed profitability.

Here, the high 61x multiple suggests the market is pricing in a sharp rebound in earnings. That premium stands out given Kuraray’s current 1 percent return on equity and thin profit margins after recent one off impacts. Versus an estimated fair price to earnings ratio of 24.6x, the current valuation implies the share price could have a long way to fall if earnings do not ramp fast enough to meet those expectations.

Relative to the wider Japanese chemicals industry on 12.5x earnings and a peer average of 20.7x, Kuraray’s 61x multiple is not just a modest premium. It is a striking outlier that demands a robust earnings turnaround to be sustainable.

Result: Price-to-Earnings of 61x (OVERVALUED)

However, slowing revenue growth or weaker than expected PFAS treatment demand could quickly challenge the premium multiple and the analyst optimism built into Kuraray’s valuation.

Another View: DCF Points to Deep Value

While the 61x earnings multiple may appear expensive, our DCF model presents a different perspective. It suggests fair value around ¥3804.78, which is roughly 59 percent above the current ¥1558.5 share price. This raises an important question: is the market overpaying based on today’s earnings, or underestimating the company’s future cash flows?
